Rear Active Assist

Rear Active Assist

If Reverse Parking Collision-Avoidance Assist detects a risk of collision with a pedestrian or an object, Reverse Parking Collision-Avoidance Assist will warn the driver with an audible warning and warning message on the cluster. When Rear View Monitor is operating, a warning will appear on the infotainment system screen.

If Reverse Parking Collision-Avoidance Assist detects an imminent collision with a pedestrian or an object behind the vehicle, Reverse Parking Collision- Avoidance Assist will assist you with braking. The driver needs to pay attention as the brake assist will end within 2 seconds. The driver must immediately depress the brake pedal and check vehicle surroundings.

Brake control will end when:

  • The gear is shifted to P (Park) or D (Drive).
  • The driver depresses the brake pedal with sufficient power
  • Braking assist has last for approximately 2 seconds

The warning will turn off when:

  • The driver shifts the gear to P (Park), N (Neutral), or D (Drive)

The brake control may not operate properly depending on the status of ESC (Electronic Stability Control).

There will only be a warning when:

  • The ESC (Electronic Stability Control) warning light is on
  • ESC (Electronic Stability Control) is engaged in a different function

Rear Warning Only

  • If Reverse Parking Collision-Avoidance Assist detects a risk of collision with a pedestrian or an object, Reverse Parking Collision-Avoidance Assist will warn the driver with an audible warning and warning message on the cluster. When Rear View Monitor is operating, a warning will appear on the infotainment system screen.
  • If 'Rear Warning Only' is selected, braking will not be assisted.
  • The warning will turn off when the gear is shifted to P (Park), N (Neutral) or D (Drive).

WARNING

Take the following precautions when using Reverse Parking Collision- Avoidance Assist:

  • Always pay extreme caution while driving. The driver is responsible for controlling the brake for safe driving.
  • Always pay attention to road and traffic conditions while driving, whether or not there is a warning.
  • Always look around your vehicle to make sure there are no pedestrians or objects before moving the vehicle.
  • The performance of Reverse Parking Collision-Avoidance Assist may vary under certain conditions. If vehicle speed is above 2 mph (4 km/h), Reverse Parking Collision- Avoidance Assist will provide collision avoidance assist only when pedestrians are detected. Always look around and pay attention when backing up your vehicle.
  • Some objects may not be detected by the rear ultrasonic sensors due to the objects distance, size or material, all of which can limit the effectiveness of the sensor.
  • Reverse Parking Collision-Avoidance Assist may not operate properly or may operate unnecessarily depending on the road conditions and the surroundings.
  • Do not solely rely on Reverse Parking Collision-Avoidance Assist. Doing so may lead to vehicle damage or injuries.

CAUTION

  • Noise may be heard when sudden braking occurs to avoid a collision.
  • If any other warning sound such as the seat belt warning chime is already generated, Reverse Parking Collision-Avoidance Assist warning may not sound.
  • Reverse Parking Collision-Avoidance Assist may not work properly if the bumper has been damaged, replaced or repaired.
  • Reverse Parking Collision-Avoidance Assist may not operate normally if interfered by strong electromagnetic waves.
  • Playing the vehicle audio system at high volume may prevent passengers from hearing Reverse Parking Collision-Avoidance Assist warning sounds.
  • Turn off Reverse Parking Collision- Avoidance Assist when towing a trailer. If towing and moving in reverse, Reverse Parking Collision- Avoidance Assist will activate as it detects the trailer.

CAUTION

Take the following precautions to maintain optimal performance of the detecting sensors:

  • Always keep the rear view camera and rear ultrasonic sensors clean.
  • Do not use any cleanser containing acid or alkaline detergents when cleaning the rear view camera lens.

    Use only a mild soap or neutral detergent, and rinse thoroughly with water.

  • Do not spray the rear view camera or the rear ultrasonic sensors or their surrounding area directly with a high pressure washer. It may cause the rear view camera or the rear ultrasonic sensors to malfunction.
  • Do not apply objects, such as a bumper sticker or a bumper guard, near the rear view camera or rear ultrasonic sensors or apply paint to the bumper. Doing so may adversely affect the performance of Reverse Parking Collision-Avoidance Assist.
  • Never disassemble or strike the rear view camera or the rear ultrasonic sensors components.
  • Do not strike or pry the rear view camera or the rear ultrasonic sensors. Reverse Parking Collision- Avoidance Assist may not operate properly if the rear view camera or the rear ultrasonic sensor(s) is forcibly moved out of proper alignment. Have the vehicle inspected by an authorized HYUNDAI dealer.
